RB4 Relay Controller Board

Looking for an easy way to turn on lights, motors or other devices with an Arduino or other microcontroller board? Are you wanting to use your servo controller board (such as Lynxmotion SSC-32) to control lights or motors? The RB4 Relay Controller provides the ability to control 4 relays independantly using only a standard 5V logic signal. Better yet, each relay has the same connector that a standard servo motor has so all you have to do is connect each relay connector to the servo controller the same way you would connect a standard servo motor. Each relay has its own input - when the input signal is at 5V (logic high) the relay is turned on and when the signal input is at 0V (logic low) then relay will be off. Any device that produces a 5V signal can be used to control these relays - Arduino or other microcontroller board, prop controller, servo controller even a simple battery and switch could be used. Each of the 4 relays provide both Normally Open and Normally Closed connections will remain in the off position if not connected. The relays are rated at 8A 240V (AC) and 5A 100V (DC).
